The gears 14 and 15 have oscillating movement imparted to them by means of a rack3 9 mounted for sliding movement in a way or groove in a side wall of the housing 13, and

was shown in Figure 4. This rack is actuated by means of a bending lever 40 ,pivotally mounted on a shaft and pivotally connected with the rack at oneiend and in operative engagement with a bending cam a l at its opposite end, said cam being secured to a cam anddriving shaft 42 mounted in the side parts 10, said cam 41 being shaped to impart timely reciprocating movement to the rack to effect the operations hereinafter set forth. The rack bars 37 are each pivotally con nected with en dvbending arms 4:34tl secured to'the rock shaft 45 mounted in the side parts 10,the arm 43 being extended to engage with an endbending cam to. The levers 40 and 43 are engaged within ca-iir grooves in the cams, whereby positive movement is imparted to the levers in bothdirections. Ver-- tical reciprocating movement of the shafts29 is effected by ineansgof placing arms L7 se cured to a placing shaft 48 mounted in bearings in brackets {l9 secured to 'tllQCI'OSS piece 30.,and as shown in Figures 2' and 9- of the drawings. Aplacing lever :50 is secured to the shaft 48-with its end iirengagement with V l the periphery of the cam all that is depressed actuate the ejector at proper times to eject ingj, and as shown in Figure 2. An ejector le- 'bentand formedstructures when they are for actuation ofthe lever 50 toimparttimeiy reciprocating movement to theshafts 29. An ejector 51 issecured to 2111' ejector shaft- 52 mounted in a bracket 53securcd'to the hour! ver 5 lsecuredlto the shaft is'extended into operative engagement with the cam d6 that has a hump 55 properly formed and locatedto formed structures fromv the benders a id formers, the ejector extending forward from thefshaft 52 into ,a position between the main benders and formers and to overlie the engaged with said bender-sand formers, and as illustrated in Figure 5 of the drawings.

Retainers 56 are secured to the under side studs 27 and'the former ribs 26.

of the housing 13,;the ends of these retainers being recessed to receive the-ends of the structures as they are bent around the formersat the ends of'tlie ribs 26, in a manner to be hereinafter described, andthereby holding the structures in engagement with the main benders andformers during the bending and forming operation. 1

The mops 3d are supplied to the ends of feed levers 57-58, in any suitable manner, either mechanically or manually, the ends of said levers being recessed to'receive the ends 33 of the mops. These levers are secured at their lower ends to a rock shaft 59 mounted in bearings in brackets 60 secured to one of the cross bars 11. The feed lever 57 is engaged, intermediate its ends, with a feed cam 61. The levers 505% -5Y are moved in one direction in opposition to the cams, or, in other words, are held in engagement with the cams by suitable springs, as shown in dotted lines in Figure 1 of the drawings, said springs, however, being omitted in other views for the sate of clearness of the showin 1 c Inthe operation of the machine the parts bein in the positions indicated especially in Figures 1, 6, 8 and 9, the levers.5758 are operated to place the ends of a mop 34 against the pins 32 opposite the space between the bending nose 31 and said pins, asclearly shown in Figure 9. The arms d7 are now actuated through the connected shafts, levers and, cams, hereinbefore described, to move the shafts 29 upwardlvthe pins 32 retreating into their recesses in this movement, as hereinbefore described. The ends of the mops are thus placed in the space between the The racks 37 are now actuated by the levers 43 and 4rd and their connections with tlle citlll 46 to rotate the end benders to bendtlie ends 33 around the formers at the ends of the ribs 26, in which lYiOVQHlGIlhSZllCl ends; are carried into the retainers 56 and held thereby, as liereinbefore described. The shafts 29 are now operatedto withdraw the end benders and the mop structure is thus held in contact with the main ,beiiders and former by the I'QtEIlDGl-Sfifi. p p

, Therack 39 is now actuated by the lever 40 and its cam ll to rotate thegears 14 and 15 whereby, tliroughtlieconnections hereinbefore described, the actuating arms 18 are swung in opposite directions to move the bendingarms 24 from the positions shown in Figure 6 to the positions shown in Figure7, in which movements the blocks 17 and 2l travel along the slots in which they are located, the relative positions of the different parts at different stages in the bending operations being shown-in Figures 5, 6 and 7, Figure 5 showing the initial relative location oftlie parts, Figure Sthe relative location of the parts after the ends'have'been on i bent, and Figure 7 the relative location just after the final bending movement of the parts. .Vhen the bending movement is completed the ejector 51 is operated by the lever d and hump to dislodge the formed structure from the forming devices andethe rack 39 is thereafter moved in an opposite direction to return the partstotheir normal positions. 1 i j l a In the forming of the main part of the mop structure the Wire or body is carried around the studs 27 as said studs are moved toward each other, and this movement is permitted by reason of the sliding bearings 17 and 21 of the stud 19 andshait 20, as here inbefore described. i
